· JVASP-126303· Ni3Ir

Ni3Ir is an intermetallic compound composed of nickel and iridium in a 3:1 atomic ratio, belonging to the class of ordered metallic intermetallics. This material is primarily investigated in high-temperature structural applications and aerospace research due to iridium's exceptional oxidation resistance and refractory properties combined with nickel's workability; Ni3Ir offers potential advantages over conventional superalloys in extreme thermal environments, though it remains largely a research material with limited commercial production.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
